Boxplot and Histogram Card Sort

Just a quick blog post today. My stats students were struggling with boxplots. So, I decided to take a break from making boxplots to letting them look at boxplots that were already made. A quick google search led me to this card sort linked to by @druinok.

I always feel so silly when I search for stats stuff and end up at her blog because she has already given me all of her stats files. Sometimes I forget to look at all my resources before turning to the almighty google!

I printed these off at the last minute and had my student aide laminate them. I gave them to my students, and they really struggled at first. The goal of this card sort was to match boxplots, histograms, and summary statistics. My students quickly matched up the median with the middle line on the boxplot. But, they struggled to figure out what to do with the mean and standard deviation. After a quick reminder of how the skew of data affects the placement of the mean in regards to the median and the meaning of standard deviation, they were able to match up most of the cards.

They also struggled at first with matching boxplots to histograms. However, after one student realized that you could match up the minimum and maximum values, the groups seemed to move along pretty well. Overall, there was lots of great conversation which was exactly what I was going for.

Just thought I'd post this in case anyone else could use this or so I can find the link next time I go looking for it!
